To cap off the evening, Prince Charles, 69, and the evening’s performers, Sir Tom Jones, Kylie Minogue, Sting and Shaggy and Craig David appeared onstage to celebrate her.

That’s when the Prince of Wales raised three cheers for his world famous mom in his heartfelt birthday speech. At first, Prince Charles called her “Your Majesty,” but then he got personal.

“Mummy,” he called her. And at that precise moment, Queen Elizabeth’s eyes got extremely wide, drawing huge laughs from the crowd.

The look spoke volumes, as she wordlessly communicated her feelings on his word choice. Was it an eye roll? No one can be quite sure.

Online, people are obsessed with the moment.
